I came across a company call Stellar Rigs who claim to be selling some pretty cool carbine conversion kits for 1911 and Glock pistol made by “Mec-Tec”
The website is out of date and I do not know if the kits are still sold. I do know that in most Western countries converting a pistol into a rifle is not allowed. UPDATE: I was wrong. See comments below.
